Rosco Manufacturing Bloodline 5.56 AR-15 Barrel - Carbine - Government - 11.5"

Note: this barrel is under 16 inches in length. The National Firearms Act regulates configurations assembled with barrels this short -- know the NFA laws in your state before purchasing.

The AR-15 is by far the most dominant carbine on the market, and simply building 'good enough' components doesn't cut it. The Bloodline series of barrels was designed and built entirely in-house by Rosco Manufacturing to outperform the competition and outlast it too.

Features:

• 11.5" barrel, Government contour
• Chambered in 5.56 NATO, 1:7 twist
• 41V50 chrome moly vanadium steel
• Salt bath nitride finish, nitride-finished M4 barrel extension
• carbine-length gas system
• .750" gas seat diameter
• Threaded 1/2x28, 11-degree crown
• 20.82 oz weight

This barrel is machined to a balanced government contour, offering a solid balance between rigidity and weight. The reliable carbine-length gas system ensures the rifle gets the right amount of gas to cycle even in adverse conditions, and the 1:7 twist rate is perfect for heavier, precision-oriented cartridges while remaining thoroughly functional with popular, less expensive bullet weights.

Rosco Manufacturing produces every barrel entirely in-house from raw steel, controlling every step of the process. Based in Central Falls, Rhode Island, every component is 100% made in America, by Americans.
